port cannot fetch because of expired cert, but cert is OK according to Safari, curl (question related to Mojave / Catalina)

[Gerben Wierda]

I contacted NLNet Labs, they updated their certs which made NSD fetch on Mojave work again for me.

Somewhere during my tests accidentally OpenSSL was activated on my machine (a destroot on nsd 4.3.8 maybe?), which killed all the installed ports that were dependent on an opensll 1.1.1 dylib (which had been made inaccessible), so suddenly a lot of programs couldn’t start anymore (Abort 6) because the dylib wasn’t there. That kind of forced me to do a quick update of everything.

So I updated NSD to 4.3.8 and created a pull request for it (as the existing MacPorts version 4.1.2 would not compile with OpenSSL3 which is now standard and I am an NSD maintainer)

That change has now been merged with MacPorts master (yes! yes! I did it correctly! I’m getting the hang of it!)

Everything NSD is back as it should be.

Normally, expired root CAs should stay in there because that allows positive non-verification of certs supposedly issued by an expired (and maybe compromised) root CA.
